Application filed December 28, 1921. Serial No. 525,488.

To all whom t may concern:

Be it known that I, MAXARDNER, `a citizen of the United States, i residing at Lock Haven,l in the 'county of Clinton and State of Pennsylvania, have invented certain new and useful Improvements in Plumbers Clamps, of which the following is a specilication, reference being had to the accompanying drawings. l p

This invention relates to wipe oint clamps and has for an important'object thereof the provision of a clamp for holding sections of lead pipe while making a'pwipe liointeonnectio'n thereof. d

A further object Vof the invention is to provide a device of this character having a minimum number of parts and which may be readilyadjusted t'o suit the requirements of the work on hand. l j j A still further objectof the inventionis to provide a device of this character in which the standards upon which Vthe working parts A of the clamp are employedmay be formed of a standard size pipe, enabling the plumber or mechanic employingthe clamp `to :cut lengths for the standards best suited to his requirements. i

VOther objects and advantages of the invention will become apparent throughout the course of the following description.

In the accompanying drawings, wherein' for the purpose of illustration'is shown a preferred embodiment of my invention, and

wherein like Vreference characters designateV like parts throughout;

Figure 1 is a side elevation partly in section of a clamp constructed in accordance with an embodiment of the invention;

Fig. 2 is a front elevation thereof;

Fig. 3 is a plan view thereof; and

Figs. 4, 5, and 6 are detailed views of the i clamping elements employed.

Referring now more particularly to the drawings, thenumeral 10 designates a suitable base having a vertical openingll therethrough, preferably of a Vsize sufiicient to permit sliding-adjustment of a piece of'one-.

quarter inch of the standard pipe therethrough. The pipe 12 maybe heldin adjusted position in the base 10 by means of a clamping screw`13 ofany desire-d construc-` ition. The base.. 10 may be secured to, any

suitable support S by means of securing elements 14 extending through openings provided in the base. The support S is preferably provided with an opening 15 aligning with the opening llof the base in order that the pipe may be adjusted not only through the base, but through the support as well.

The pipe 12 or vertical' support employed has its upper end threaded for the reception of a threaded head 16 shown in the present instance as provided with a pair of upstanding ears 17, the opposed faces of which are corrugated.` One of the ears 17 has an opening formed therethrough and theotherof the ears has an opening aligning with the first named opening and interiorly threaded and engaged by a clamping Vscrew 18. It will be obvious from an inspection of the drawings that the head 17forms one piece of the two piece swivel clamp. An arm 19 is provided having upon one end thereof a casting 20 provided with an extension 21 corrugated upon its opposite faces and forming the other piece of the two piece swivel clamp, this extension 21 having an opening through which the clamping bolt 1S may extend. The opposite end of the arm 1S) is provided with ahead 16 similar to the head provided upon th'evertical standard 12.

'In accordance with my invention, I also provide a pipe clamp C comprising a pair of clamping members 22 and 23 adapted to be arranged upon opposite sides of the piece of pipe to be held and assembledthereabout by means of bolts 24C having wing nuts 25, by means of which the clamp may be tightened. The clamp section 22 is provided with an. extension 26 corrugated upon its opposite faces and likewise adapt'ed to form the second piece of the two piece swivel clamp hereinbefore mentioned. Y It will be obvious from .the foregoing that either the arm 19 may be engaged with the head 17 upon the standardV 12 or the clamp C may be engaged therewith. If desired, the arm 19 may be engaged with the head 17 of the vertical standard and the clamp C engaged with. the head 17 of the arm. Since the standard 12 is circular in cross section and may be readily rotated within the base 10 and the arm 19 may be adjusted at any desired angle thereto, itpwill be seen that the arm 19 may be positioned at any desired direction. The engagement of the head 17 with the arm 19 is threaded 'as in the case of the engagement of the head 17 with the standard 12 so that these heads are interchangeable. The casting 2O previously mentioned has a slip joint connection with the arm 19 and a thumb screw 2].a by means of which the arm 19 may be clamped in position. Accordingly, a clamp C'Inay be engaged with the head 17 of the arm 19,

turned in any desired position and angle and clamped in such angle. It will accordingly be seen that in the formation of wipe joints it is possible to bend the pipe employed to the desired curvature and then hold the sections in their proper position by the clamp.

In the use of the device, three of the bases 10 will be employed, 'each provided with a standard 12 having a head 17 thereon. W'ith twootthese heads, a clamp .C may be engaged to hold the T-head of the wipe joint and with the other an arm 19 will be employed having a clamp C engaged with the head 17 thereon. The arm 19 as previously stated may be adjusted to any desired position to hold the stem pipe of the T-head in the proper position for forming a wipe joint regardless ot' whether the pipe employed is straight or bent.

It will vbe obvious that the head 17 and bases 10, together' with the castings 21 being adapted for use for the standard sizeV i* ing Jfrom the spirit of my invention, and I accordingly do not limit myself to the specie structurel thereof except as'hereina'ter claimed. Y

1. In a plumbers .clamp for use in joint wiping operations, a base adapted for Vmountino' upon a suitable support, a. meminterchangeable engagementwith said head,

and a head similar to the first-'named head atone end of said arm, said arm 'being ro tatable in the extension, thereof andmeans for locking the arm against rotation.

2. A plumbers clamp for use in joint wiping operations comprising three base members adapted for mounting upon a suitable support, members adjustable through said base members and each provided with a head vforming one piece of a two-piece swivel clamp, an arm having an extension forming the other piece of the two-piece swivel clamp engaged with one of said heads and Vpruvided upon its free end with a head similar to said heads, and clamps engaged /with'the nast-nained. headV andthe heads of the remaining members, said clamps each being provided with an fextens'ion forming. the other piece ofthetwo-piece swivelV clamp.

In testimony whereof I hereunto affix my f signature. Y
